Abstract (en)
[origin: WO9833266A1] As a front end power factor correction circuit in a rectifier a boost conversion topology is often used. A great problem with this topology is the rectifier diode. This diode must be of a high voltage type in a boost application and will therefore have a large reverse-recovery current before it will block the voltage. This current may cause large losses. With the solution according to the invention care will be taken to the recovery current in a more effective way than any earlier solution has obtained. The proposed circuit comprises essentially a boost circuit, where a main and first inductor L1 (3) and a main and first diode D1 (4) are connected in series from an input to an output and a main and first capacitor C1 (5) from an output to ground. A main and first transistor M1 (1) is connected from between the first inductor L1 (3) and the first diode D1 (4) to ground. An auxiliary and second inductor L11 (6), a second diode D11 (7) and a second transistor M11 (2) are connected in series from between the first inductor L1 (3) and the first diode D1 (4) to ground. Two other diodes a third and fourth diode D12 (10), D13 (9) are connected in series from between the second diode D11 (7) and the second transistor M11 (2) to the output.
